Description

To proceed with implementing FanPT capabilities in PyCI, we need to calculate the derivatives of the overlap matrices.
This feature is already implemented for AP1roG, but is not currently available in the code for pCCD+S.

Research direction

Locate the existing AP1roG overlap-derivative implementation and the corresponding pCCD+S code, then compare how the derivative calculation is represented. Done means pCCD+S exposes the required overlap-matrix derivatives so FanPT implementation can proceed; no file or test is named in the issue.
